EXPLAIN WHAT IT IS, HOW IT TRAVELS THROUGH AIR AND WATER, PITCH, HOW IT TRAVELS THROUGH YOUR EAR. Chapter 5 - Physical Science "Sound"
When we think of sound we think of the most obvious, that it is some type of noise that we hear with our ears. However, sound is much more than that as there is a lot involved. Just by asking simple questions you can find out much more about the subject. For example, what is sound? How does it travel? How does it travel through the ear? Is it present everywhere? Finally, how can we, as future teachers, teach sound? To begin, let’s define what sound is. Sound is a series of vibrations that can be heard when they reach a person or animal’s ear. Sounds can vary and there are countless examples of them. Human voices, music, a bang of some sort, animal noises, these are all examples of sound.
Next, how does sound travel? Sound is transmitted when the atoms or molecules in the object solid, liquid, or gas, collide with each other. However, it is the wave of energy rather than the molecules that travel at a great distance. Although sound may travel through many materials, in order for us to hear it, it will have to travel through the air to reach our ears.
Now that we know how sound travels, let’s ask how does sound travel through the ear? When sound reaches the ear it is collected by the external portion of the ear and then passed through the meatus (auditory ear canal). The sound is then transferred to the middle ear through the ear drum where it encounters three small bones that vibrate. These bones are the malleus (hammer), the incus (anvil), and the stapes (stirrup) which function to magnify sound. This area connects to the inner ear which is made up of the cochlea, three semicircular canals, and the vestibule. The area responsible for transmitting sound is the cochlea which has the nerves that travel to the brain. The other two segments of the inner ear are primarily responsible for balance.
Another question that we can ask, is sound present everywhere? That answer, is no. No, sound is not present everywhere. There is no sound heard in space. This is because sound can only travel through a medium such as a solid, liquid or gas by making molecules vibrate, and there is no air in space for sound to travel through. Because space is an almost perfect vacuum, sound waves cannot travel through it.
As future teachers how can we teach sound? There are several experiments that a teacher can use. One experiment that you can use to teach sound involves a balloon. This can be found at the link below:
After the students do this experiment have them answer questions like these:
What is going on when you talk into the balloon?
Why can the other person hear and feel your voice?
Try the same thing with a piece of paper. What are your results??
Does the balloon being so thin matter in this experiment? Why or why not?
In some very noisy places, like airports sound can cause trouble to buildings. Can you think how?
Here is a video clip that sums it all :o)
